, BeitknownthatLWILLIAMWEi/vnnsncitizen of the United States, residing at'Quincy, in the county of Adams and State of Illinois, have invented new and useful Improvements in Grates, of which the following is a specification. I.

Thisinvention relates to grates, and it is capable of use in connection With various kinds of stoves, furnaces, and like apparatus, the object of the invention being to provide a simple article'of this character which is adapted effectively to burn either Wood or coal or their equivalents, the grate being adapted to be shiftably mounted in the fire-box of a stove,

furnace, or the like in order that the wood and coal burning sections thereof can be alternately vand readily brought into position for use.

The wood and 4coal burning sections of the grate are arranged at an acute angle with respect to each other, by virtue of which said grate as a whole occupies but a very small space within 'the fire-box of a stove or its equivalent, and'said sections are of approxi- Y it has upon its working face means forholdin gthe Wood or analogous combustible out of direct` contact with said face, and hence away from the ashes that accumulate on the latter in use. The said means also lpermit the circulation of air under the wood in orderto secure the highest degree of coinlnistion. The

coal-burning section of the grate is of barred construction. ln the drawings accompanying and forming a part of this speciiication, Figure l. is aplanA Like characters refer to like parts in the several figures.

The duplex grate includes in its construction Wood and coal burning sections denoted, respectively, by 2 and 3 and shown as located at an acute angle to eachother. The sections are united upon their Inner faces substan-` tially centrally thereof and also at their ends by the Webs 4, which strengthen the compound grate, and the end Webs are provided with laterallyextending journals or gudgeons 5, upon their outer faces adapted to be sustained for` rocking motion by suitable bearings on or in a stove, furnace, or equivalent device,'it being seenthat said journals or gudgeons are located substantially centrally of the Width ofthe grate-sections.

The two grate-sections 2 and 3, the Webs 4,

and the journals 5 are usually Inadeintegral'- and can be inexpensively produced by casting. Oneof the journals isshown as longer thanthe other, so that the outer end of the same can extend beyond'the stove to receive a suitable implement for operating the grate.

The Wood-burning section 2 of the grate has `perforations 6 of a desiredv number, through which atmospheric air can ascend When 'said section i is in use, it being understood that during such operation the said section 2 is horizontally disposed, such air promoting` combustion of the Wood fuel. VVood-ashes can be discharged -throu gh these perforations. The Wood-burning section is provided with means for holding the Wood thereon out of contact with the Working face thereof, and consequently away from or above the ashes that accumulate thereon, and in the present ease the said section is shown as provided with ribs? for this purpose. Said ribs extend entirely across the outer face of the section 2 and are separated a suitable distance apart longitudinally of the latter and project from said face the desired distance. When the section 2 is'in use, it is in a horizontal position and the wood is laid upon these trans' versc ribs, which latter hold the Wood above and, also to permit the circulation of the draft under such wood.

he outer side of the" grate?at 'the vjuncti'onof the twofsectionsoffthe same, is a 'lug' 8; against y;hich'asuitableinstrumentcau be placed to' facilitate the-'turn'mg'ofV said grate,Y while the section 2 ,0f-the' latter is f; "I equipped witlrjalileflug 9 for a.likepurpose.Iv

j Whenftheswoodfburning section 2is-,hori-l4 zfontallyfdis'posed, the draft enters the -fireboxofthe stove'fin' wliehfthe grate isd'nstalled,r through the usual 'damper controlled openingsfof said stove,` and'passes into the 'spaceA l between said sectionq2and the companion section l3 and rises through "the 'draftopenf ings or 'perforations 6 in the former in order o v 4.' `Agrate consistingof v ood andcoa-lburn- 465- feLy ashes-frein the wood are discharged f through thesaid openings 6 andfall through i the spaces betweertnebars ofthe 'section-3 'to' securethe proper combustin ofthe vvood `.in-tothe ash-pitjofsad stove. v4By tilting thej. section 2 the mass snppo'rtefd thereon be I emptied into the'ash-'in t.l .It it lbe desired to `i'lipped a distance sufficient to briiig the samer. into .horizontalposition By rocking thejgrate the separation-of the ashes from the live fuel'f on the section 3 can bereadily'accomplished. My improvedgrate, it will therefore be seen, is of substantially V form, the parts ,thereof being capable 'of supporting, respectively, Wood and coal and being adapted tobe readily broughtinto position alternately for use when desired. vIt is strongaud is adapted to secure the proper consumption of the respective fuels and' disposition of th'ashes Aiu eachcase.

claims.v c
